Have cooked ribs a few times SV with pretty good results have been meaning to try a smaller packer sometime.
Just came across some info from a Facebook group "Cooking with Joule" where somebody did one, he has a great write up in the File section for the group were he details every step of the process, from dry brining to the different SV temps, and times and then the finish on the smoker.
I think its titled "Adventures with brisket" definitely worth a read
